(Sharecast News) - Major indices were mixed early on Tuesday as a global sell‑off in chip names deepened and Asian markets were hit hard overnight.

As of 1520 BST, the Dow Jones Industrial Average was up 0.09% at 51,761.38, while the S&P 500 shed 0.76% to 7,416.12 and the Nasdaq Composite came out of the gate 1.18% weaker at 25,858.77.

The Dow opened 48.67 points higher on Tuesday, extending gains recorded in the previous session.

Tuesday's early losses were primarily driven by memory‑chip makers, with Micron down 7.81% at the open, while Sandisk dropped 10.28% and Seagate slid 6.24%. Intel was down 2.58%, and AMD and Qualcomm lost 5.04% and 6.81%, respectively.

Wall Street's weakness at the open also extended beyond semiconductors, with Alphabet slipping another 0.59% after a 5% fall on Monday amid concerns over high‑profile AI talent departures.

The broad retreat follows a sharp reversal in tech sentiment that began at the start of the week and has since accelerated across global markets, with South Korea's benchmark, which was up 95% this year, down almost 10%, while Japan's Nikkei 225 shed 3.55% - breaking an eight sessions winning streak.

On the macro front, US business activity picked up in June, with preliminary data from S&P Global data showing manufacturing, services and the overall US economy all growing at their fastest pace in several months. S&P Global's manufacturing purchasing managers index rose to 55.7 from 55.1 in May, beating expectations and marking the strongest reading since May 2022. Elsewhere, the services PMI edged up to 51.3 from 50.7, slightly above consensus and signalling the fastest rate of expansion in four months. Together, the moves lifted the composite PMI to 52.2 from 51.5, the strongest pace of private‑sector growth since January. S&P Global said the improvement reflected a six‑year high in manufacturing output and firmer services activity.

On another note, the Federal Reserve's Fifth District manufacturing index fell sharply in June, dropping to 4 from 13 in May, the Richmond Fed said on Tuesday, indicating modest growth but also poining to a clear loss of momentum.

In the corporate space, FedEx will publish its latest quarterly earnings report after the close.
